Context Before

VR Max-Q on the other hand, exhibits lower Operating costs relative to MI4XX given the lower chip TDP. For example a VR NVL 72 cluster deployed at a Hyperscaler with Arista networking would have a operating cost of $0.75 per gpu per hour, representing ~20% lower costs vs MI4XX deployed with a Hyperscaler with the same Arista networking.

Evidence

This highlights the advantages of the Max-Q configuration, particularly from an operating cost perspective, as the lower power TDP reduces rack-level power density for a meaningful cost savings over time.

Context After

The MI4XX currently has a performance per TCO advantage based on marketed dense FLOPS over VR. VR has a higher TCO per GPU compared to MI4XX, yet VR marketed PFLOPs are lower vs MI4XX resulting in a TCO per PFLOP disadvantage for the VR vs MI4XX.

② Atomic Claim

這凸顯 Max-Q configuration 在 operating cost 上的優勢：較低 TDP 會降低 rack-level power density，長期可帶來顯著成本節省。
